One purpose of such control is, for example, the slippage between the drive wheels of a motor vehicle driven by a drive machine and the track.

In the known device, a first driver is connected to the operating element, a second driver is connected to the control element, 111
A third driving body, which acts the force of the one-bar motor on the control member, and a return spring, which operates the third driving body towards the rest stop, are combined in the area of the control member. If the control element is a throttle valve, said component is located directly in the intake pipe of the engine.

However, in the area of the intake pipe there are often very limited installation situations, so that it is difficult to find sufficient space for the known device or for the intake pipe. It is not possible to select the optimal layout format.

SUMMARY OF THE INVENTION It is therefore an object of the invention to avoid the above-mentioned disadvantages of known devices.

In order to achieve this object, the invention provides that in a device of the type mentioned at the outset, when the actuating member of the adjusting motor is inactive, the return spring causes the direction of the reduction in the power of the drive machine to be adjusted. The adjusting motor with the actuating member, the return spring and the rest stop provide an adjusting mechanism which can be arranged at a distance from the control member. It is formalized.

Advantages of the Invention With the embodiment of the invention, the disadvantages of known devices can be reliably avoided and the adjustment mechanism can be arranged at a suitable location remote from the control element.

Further advantageous embodiments of the invention are described in the subclaims.

If the actual value transmitter is arranged on the adjustment mechanism, the control and electrical engineering effort is considerably reduced, so that the detection of the adjustment position can be simplified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made to an advantageous embodiment of the invention shown in the drawings, which comprises an adjusting motor acting on the transmission device 2 between the operating element 4 and the control member 8 which defines the output of the drive machine 6. In addition, the structure and mode of operation of a device constructed according to the invention in a machine, in particular a motor vehicle, will be explained in detail. The device according to the invention can be used in any machine that has a drive machine 6 and in which adjustment of the drive machine is desired. The machine may be stationary or, for example, a self-propelled machine or a motor vehicle. However, in the description of the exemplary embodiment, for reasons of simplicity, the device according to the invention is installed in a motor vehicle with an engine.

The transmission device 2 essentially has a transmission element 12 , a first driver 14 , a second driver 16 and a coupling spring 18 .

The first driver 14 is connected to the actuating element 4 by means of the transmission element 12, and the control element 8 is connected to the second driver 16.

The connecting spring 18 acts on the first driving body 14 on the one hand and on the second driving body 16 on the other hand, so that the first connecting stop 20 of the first driving body 14 is brought into contact with the second driving body 16 of the second driving body 16. The two driving bodies 14, 16 are moved relative to each other until they come into contact with the connecting stop 22 of.

The control member 8 is, for example, a throttle valve integrated into the suction pipe 24 . Depending on the adjustment position of the throttle valve 8, it is possible, for example, to influence the flow of the air-fuel mixture into the drive machine 6 through the intake pipe 24 (see arrow 26).

As a result, via the adjustment position of the throttle valve 8,
The output of the drive machine 6 is controlled. Arrow 2 shown in the drawing
Actuation of the throttle valve 8 in the direction of 8 means an increase in the power of the drive machine 6, and actuation of the throttle valve 8 in the direction opposite to the arrow 28 means a decrease in the power of the drive machine 6. Control element 8 can be actuated in the direction of arrow 28 by means of actuating element 4 via transmission device 2 . In the direction opposite to the arrow 28, the control member 8 can be actuated by means of a return spring 30 provided on the transmission device 2.

The return spring 30 acts on the wall 32 on the one hand and on the first driver 14 on the other hand. Return spring 30 is indicated by arrow 28
acts on the first entrainer 14 in the opposite direction. In addition to or instead of the return spring 30, a further return spring 34, shown in broken lines, may be provided. This further return spring 34 likewise acts on the wall 32 on the one hand, and on the other hand the second driver 1 in the direction opposite to the arrow 28.
6. Depending on the action of the actuating element 4, the two return springs 30, 34 move the driver 14 in the direction opposite to the arrow 28.
', 16 and throttle valve 8 can be operated. This operation continues until one of these parts contacts the adjustable idle stop 36.

In the illustrated embodiment, the first driver 14 is configured in such a way that it rests on an idle stop 36 .

The force of the coupling spring 18 is exerted by the third driver 40 without the influence of the transmission device 2, so that the first coupling stop 20 of the first driver 14 is always applied to the second driver of the second driver 16. It is arranged to come into contact with a stop 22 so that the adjustment position of the actuating element 4 can be transmitted to the control member 8 via the transmission device 2 .

Furthermore, the third driver 40, which is provided with a third driver 40, has a stop 42, and the second driver 16 has a stop 43. When operating the third entrainer 40 in the direction opposite to the arrow 28, the second entrainer 1
Depending on the adjustment position of 6, the stop 4 of the third driver 40
2 can contact the stop 43 of the second driver 16. If the third driver 40 is further actuated in the direction opposite to the arrow 28, the second driver 16 is likewise driven in the opposite direction to the arrow 28. The third driver 40 is the adjustment mechanism 5
Operated by 0.

The adjusting mechanism 50 essentially has an adjusting motor 52 with an active member 54, a return spring 60 and a rest stop 63, and optionally also an actual value transmitter 69. Adjusting motor 52 is, for example, a rotary motor, in which case active member 54 is a rotary shaft. Also, the adjustment motor 5
If 2 is a near motor, for example a hydraulic cylinder, the working member 54 is a piston rod. Acting member 5
4 can, for example, itself directly be the rotational axis of the adjusting motor, or a transmission 74 can be interposed between the actuating member 54 and the actual motor 72 of the adjusting motor 52 and the actuating member 54. In this case, the active member 54 is the output shaft of the transmission 74. The operating member 54 of the adjustment mechanism 50 is
It is connected to the third driver 40 by a transmission means 76 . The transmission means 76 is, for example, a rod, a Bowden cable, a Seil cable, or the like. When the transmission means 76 is, for example, a Bowden cable or a Seil cable, the third
A tension spring 78 is provided between the third driver 40 and the wall 32 and acts on the third driver 40 in the direction of the arrow 28.
The tension spring 78 serves for a minimum tension in the transmission means 76, ie the tension spring 78 prevents, for example, the cable from sagging.

The tension spring 78 can be constructed relatively small and weak. This is because the tension spring primarily only needs to compensate for the frictional forces acting on the third driver 40 and the transmission means 76. Regarding the construction of the transmission means, it is possible to omit the tension spring 78, for example if the transmission means is a rod.

The return spring 60 is connected on the one hand to the casing 8 of the adjustment mechanism 50
2 and, on the other hand, the actuating member 54 in the direction of the arrow 28 to actuate the actuating member 54 of the adjusting top 52 towards the rest stop 63 . Depending on the use case of the device according to the invention, this function may be omitted, in which case the return spring 60 can be omitted.

The actuating member 54 of the adjusting mechanism 50 is controlled by the actual value transmitter 69.
The adjustment position can be detected. When the adjusting motor 52 is controlled, the stop 42 of the third driver 40 and the stop 43 of the second driver 16 are in contact with each other, so that when the adjusting motor 52 is controlled, the actual value transmitter 69
The adjustment position of the second driver 16 and thus of the control element 8 can be detected at least indirectly. It is true that the area of the control element 8 is often already provided with an actual value transmitter for detecting the adjustment position of the control element 8, for example for the purpose of adjusting the fuel metering; however, this actual value transmitter is For electrotechnical reasons, the device is not very suitable for detecting the adjustment position of the control element 8 for the purpose of controlling the adjustment motor 52. It is particularly advantageous to arrange the actual value transmitter 69 in the region of the adjustment member 50, since a narrow installation often exists in the region of the control member 8. In some cases, for example for reasons of reliability, it may be advantageous if two actual value transmitters 69 are provided.

In the device according to the invention, two different operating states may exist. The first operating state is an uncontrolled operating state. In this case, the adjusting motor 52 of the adjusting member 50 is not controlled. In the first operating state, the control member 8 can be brought into the respective desired adjustment position by the actuating element 4 without being influenced by the adjustment mechanism 50. In the first operating state, the active member 54 of the adjusting motor 52 rests on a rest stop 63 .

Due to the transmission means 76 and the optionally provided tension spring 78, the third driver 40 occupies a rest position, that is, the third driver 40 is operated as far as possible in the direction of the arrow 28. ing. Based on the distance between the stop 42 of the third entraining body 40 and the stop 43 of the second entraining body 16, the stop 42 of the third entraining body
is the stopper 4 of the second driver 16 in the first operating state.
Do not touch 3.

Control member 8 of operating element 4 in the direction of arrow 28
As the operation of , the output from the drive machine 6 is increased.

At this time, a sensor (not shown) can be used to detect slippage between the drive wheels (not shown) and the running ground. Such slippage is extremely disadvantageous. In order to avoid this slip, the adjustment mechanism 5
0 adjustment motor 52 is controlled via an electronic control unit, not shown. In this case, the device according to the invention operates in a second operating state, which can be called a controlled operating state. In the second operating state, the regulating motor 52
The active member 54 is connected to the third driver 4 via a transmission device 76.
0 in the direction opposite to the arrow 28, the stop 42 of the third driver 40 can come into contact with the stop 43 of the second driver 16.

If the third driver 40 is actuated further in the direction of the arrow 28 by means of the actuating member 54 of the adjusting mechanism 50, the second driver 16 and thus the control member 8 also move in the opposite direction to the arrow 28, i.e. the output of the drive machine 6. Manipulated in the direction of decrease. The control member 8 is then actuated in the direction of the arrow 28 until a sensor (not shown) detects no unacceptably large slip between the drive wheels and the road surface.

The transmission means 76 can be shifted very flexibly, depending on the embodiment. Due to the fact that the return spring 60 and the rest stop 63 as well as the actual value transmitter 69 can be arranged spatially independent of the intake pipe 24, the installation of the intake pipe 24 with the control element 8 is possible in an advantageous manner. is significantly simplified. Furthermore, it is particularly advantageous if the return spring 60 and/or the rest stop 63 are combined together with the adjustment motor 52 in the adjustment mechanism 50. The adjustment mechanism 50 is advantageously a compact unit and can be arranged at a more or less large distance from the intake pipe 24 if desired.

The connection between the adjusting mechanism 52 and the third driver 40 and thus, depending on the control of the adjusting motor 52, with the transmission device 2 is effected by means of the transmission means 76.

The return spring 30 is connected to the connection spring 1 with respect to another return spring 34.
This provides the advantage that 8 can be constructed weakly. Furthermore, in the illustrated embodiment, the influence of the adjusting mechanism 50 on the actuating element 4 is relatively weak and the forces exerted on the adjusting mechanism 50 in the second operating condition are relatively small. An embodiment with a linear direction of movement parallel to arrow 28 is described. In other embodiments of the device according to the invention, at least some of the components may optionally not be movable linearly, but instead be mounted pivotably.

In this case, a movement in the direction of arrow 28 means a pivoting movement in one direction, and a movement in the opposite direction to arrow 28 means a pivoting movement in the other direction. Since the control element 8 is normally rotatably mounted, it is also possible to rotatably support other components.

This is Figure 18.
